AUTOMOBILE-JACK.

Specification of Letters Patent.

Patented Feb. 28, 1911.

Application filed March 4:, 1910. Serial No. 547,265.

To all whom it may concern: Y

Be it known that I, \VILLIAM F. SCHREI- mm, a citizen of the UnitedStates, residing at Cedar Rapids, in the county of Linn and State ofIowa, have invented a new and useful Automobiledack, of which thefollowing is a specification.

This invention relates to jacks especially designed for use inconnection with automobiles.

It is a well known fact that when automobiles are used for displaypurposes within sales-rooms, the tires thereof often become injuredbecause of the constant unshifting weight to which they are subjectedand because of the further fact that they become flattened because ofdeflation.

One of the objects of the present invention is to provide a jackparticularly designed for supporting an automobile out of contact withthe surface upon which it is mounted, the jack being of a simple andcompact construction and easy to operate.

A further object is to provide a device of this character which can bereadily adjusted for use in connection with wheels of differentdiameters.

lVith these and other objects in view the invention consists of certainnovel details of. construction and combinations of parts hereinaftermore fully described and pointed out in the claims.

In the accompanying drawings the preferred forms of the invention havebeen shown.

In said drawings :Figure 1 is a side elevation of a jack constructed inaccordance with the present invention the position of said jackimmediately prior to the elevation of the wheel being indicated by fulllines and the relative positions of the parts, when the wheel iselevated, being indicated by dotted lines. Fig. 2 is a plan view of thejack showing the parts in their normal positions. Fig. 3 is a section online i k-13 Fig. 2. Fig. 4 is a detail view of the hub engaging block ofthe jack. Fig. 5 is a transverse section through the block. F O is aperspective view of a portion of a modified form of jack.

Referring to the figures by characters of reference 1 designates thebase of the jack,

the sides thereof preferably converging toward one end and each of saidsides being provided with a longitudinally extending shoulder 2 inclineddownwardly toward the small end of the base.

Eyes 3 or the like are arranged upon the base and a rod 4: extendsthrough them and projects into opposed portions of a bail 5 constitutingthe actuating lever of the jack. Each end of the bail has an arm 6extending therefrom and the said bail, when in its lowermost position,is designed to rest upon the shoulders 2 and thus support the arms 6 ininclined positions as shown by dotted lines in Fig. l.

The arms (3 are formed with apertures 7 each of which is designed toreceive a trunnion 8 extending laterally from the lower end of a framemember 9. These frame members converge upwardly and merge into parallelextensions 10 designed to rest within grooves 11 formed longitudinallywithin the sides of a hub engagin block 12. The ends of this block areprererably concaved as shown at 13 and extending through the block fromone groove 11 to the opposed groove, is an opening 14:. This opening islocated nearer one end of the block than the other and is adapted toreceive an arm 15 extending at right angles from the extension 10 of oneof the frame members 9. The free end of the arm 15 is adapted to projectinto an eye 16 formed at the free end of the extension 10 of the otherframe member 9 and this end of the arm is preferably screw threaded andadapted to be engaged by a nut. 17. Vhen this nut is tightened on thearm 15 it serves to draw the two extensions 10 tightly into the grooves11 and thus hold the block 12 securely fixed relative to the framemembers 9.

In using the jack the broad end of the base 1 is placed close to thelower portion of the wheel and the bail 5 and frame members 9 are swungupwardly so as to thus lower the arms (3 and bring the block 12 underand close to the hub of the wheel. This hub has been indicated at C inFig. 1. The bail 5 is then swung down onto the shoulders 2 and thiscauses, the arm 6 to swing upwardly and outwardly and the block 12 istherefore pressed upwardly againstthe hub and will lift the wheel oil ofthe floor. The frame members 9 will swing laterally at their lower endsand it will be apparent t-l'lerefore that the jack will lock itself soas to prevent the wheel from returning to its lower position as long asthe bail 5 rests on 'wardly toward the wheels the shoulders 2. Obviouslyby using one of these jacks in connection with each wheel of theautomobile, the entire machine can be held off of the floor or ground.

is heretofore pointed outthe arm exten ls through the block 12 at apoint nearer one end than the other of said block. it will be apparenttherefore that with one end of the block uppermost the jacl; will beadapted for use in connection with a wheel of one diameter, while, byloosening the arm 15 and reversing the block and then tightening thearm. the jack can be used with a wheel of another diameter.

instead of utilizing a reversible block such ...i, I as snow 11 in 1gs.to lntiusn e, tne aims ti an be arranged to IQL'OH'Q a rod 18 on theends of which are mounted the ends of a frame 19 carrying a yoke 20adapted to engage the wheel hub. The said frame may be provided with oneor more openings in each end thereof and the rod can be extended throughany of these openings so as to adapt the jack for use in connection withwheels of different diameters.

It will be seen that a jack such as has been described is very simple inconstrue tion. durable and inexpensive and can be readily actuated. Byreason of the peculiar arrangement of the parts the automobile or othervehicle supported thereby is prevented from shifting laterally. masnnichas the frame members 5) wlich are inclined upsupported thereby, serve toprevent lateral movement. Importance also attached to the fact that thejack is very light and can therefore be easily -arried and placed inposition.

Various changes can of course be made in the construction andarrangement of the parts without departing from the spirit orsacrificing any of the advantages of the invention as defined in theappended claims.

hat is claimed is 1'- l. A jack including a base having inclined sideshoulders, a bail like elevating device fulcrumed on the base andnormally embracmg said base and bearing on the shoulders, armsupstanding from said device, and a wheel engaging element adjustablyconnected to the arms. s

2. A jack including a base, an elevating element. thereon, frame membersextending from and adapted to be shifted by said element, and a wheelengaging device mounted between said members, said device beingreversible to vary the distance between its upper end and the base.

A jack including an elevating lever, opposed frame members pivotallyconnected thereto, an arm upon one of the members and detachablyengagingthe opposed member, a reversible wheel engaging block mounted ot fcenter upon the arm, said block having opposed grooves for the receptionof the "rame members, and means engaging the arm and one of the framemembers for binding said members'within the grooves to hold the blockagainst movement relative thereto.

4. A jack including a base having inclined side shoulders. a bail-likeelevating device fulcrumed on the base and normally embracing said baseand bearing on the shoulders, nmvardly converging frame memberspivotally connected to the elevating device, and a wheel engagingelement carried by said members.

5. A jack including converging frame members, a reversible wheelengaging block interposed between the members and having grooves for thereception of said members, means for securing the members within thegrooves, a base, and means upon the base for elevating the framemembers.

In testimony that I claim the foregoing as my own, I have hereto atlixedmy signature in the presence of two witnesses.
